Glass Paper Weight

I have a small glass paper weight that I got years ago, it's probably the width of golf ball and has a lovely curved shape up top. After I get turned on (usually by reaing some stories here) I take a glass paper weight that I have and place it right on my clit. The cold feeling of the glass gets me excited every time and as I move it back and forth it glides effortlessly over my clit and gives me a great orgasm!
